Canadian Study Finds Neonicotinoid Pesticides Threaten Wild Birds

A University of Saskatchewan study published in the journal Science found that neonicotinoid pesticides could be responsible for a decline in wild songbird populations. Using new tagging and tracking technologies, researchers found that white-crowned sparrows who consumed small doses of imidacloprid suffered weight loss and delays to their migration. “Our study shows that this is bigger than the bees—birds can also be harmed by modern neonicotinoid pesticides, which should worry us all,” said one of the study’s co-authors.
